Last month, Sprint served up a dose of Jelly Bean for its variant of LG's Optimus G, and today it appears that AT&T is following suit. We've received a flurry of tips and screenshots like the one above denoting that Ma Bell is slowly starting to trickle out Android 4.1.2 to its Optimus G owners. Seeking confirmation, we've reached out to AT&T and will provide an update of our own once we receive official word on the matter. Until then, if you're rocking an Optimus G on Big Blue's network, now might be the time to manually check your device for new software.
